A top police officer accused of keeping twin sisters as mistresses has been sacked after the news of the scandal broke online.

The scandal involving Qi Fang, director of public security bureau of Wusu City, Xinjiang Uygur Autonomous Region in northwest China broke online last
week. It also emerged that he had used his power to give jobs to both sisters in the police force.

“Qi was accused of abusing power to give jobs to twin sisters he has been keeping as mistresses. The informer's post and the photo of two scantily-clad girls in bed quickly became a hit before they were removed from iyaxin.com, one of the largest Internet portals in Xinjiang,” state-run Xinhua reported.Online posts also claimed that Qi rent a high-end apartment unit for the sisters in downtown Wusu and reimbursed the rent as an official expense.

A provincial official said that "part of the online allegations" were true but many claims and details "remain unverified."

According to Xinhua, Qi was the latest to fall in China's sweeping "cyber-anti-corruption" drive that has notably been gathering steam since the 18th National Congress of the Communist Party of China (CPC) held in November.

“A handful of officials have been removed from their posts for being caught in sex tape shots, keeping mistresses, and owning large number of properties. All the allegations were exposed on the Internet and the authorities responded with serious probes in relatively short time -- in one case, the sacking came in some 60 hours after the Internet post first appeared,” the report said.

Lei Zhenfu an official in Chongqing was sacked last month after a video showing him having sex with an 18-year-old was released by a whistle-blower. The sex tapes were also linked to a blackmail scheme involving corruption and abuse of power.

Hu Jintao warned at the CPC congress that corruption could lead to the collapse of the Party and the fall of the state.

Xi Jinping, who took over Hu as the general secretary of the CPC Central Committee, named corruption on top of the many pressing problems within the Party that need to be resolved in his first speech after being elected to the top post.
